Bond pad of semiconductor device and method of fabricating the same

摘要

A bond pad of a semiconductor device capable of restraining dishing and having improved conductivity by a damascene technique using a copper pattern, includes first and second copper patterns of irregular lattice models, first and second dielectric layer patterns to connect the first and second copper patterns in the vertical direction, a line connection structure horizontally connecting the first and second copper patterns, and a conductivity improving layer formed on the first and second copper patterns. Dishing generated in planarizing the first and second copper patterns by a damascene technique can be restrained due to the first and second copper patterns of the lattice models. Also, the conductivity property of the bond pad can be improved by connecting the first and second copper patterns horizontally and in the vertical direction and further forming the conductivity improving layer on the first and second copper patterns.
